- frame_sudo (scripts/_env.sh) replaces three copies of sudo_run. On
the Frame it asks in the terminal even when stdin isn't one, which
install.sh's steps never had: saying yes to the Bluetooth fixes or
hand tracking stopped the install with "no terminal for sudo".
From a PC it asks through ssh -t when .env has no password.
- start_with_steamvr: the pointer, power, and gaze services restart
when SteamVR runs (a re-install runs the new code) and are left to
start with it when it doesn't, instead of failing the install.

frame-eyes, a separate project until now, becomes gaze/tracker:
- ft-eyegrab (was fe-bufprobe) copies the eye-camera frames, read-only, out of
SteamVR's eyetracking process. It runs as the system service
frametop-eyegrab.service, which gaze/tracker/install.sh installs to
/etc/frametop with sudo. It keeps only CAP_SYS_PTRACE, CAP_DAC_READ_SEARCH, and
CAP_CHOWN, and copies frames only while /dev/shm/frametop-eyes-want is fresh,
holding none of the tracker's buffers otherwise.
- ft-eyes (was fe-trackd) runs under ft-gazed in the dev container, with
build/venv's pinned numpy and OpenCV: while Eye tracker is Own tracker, or on
the probe's lease ("eyes SECONDS"). No sudo password or fe-live script at
run time any more.
- lab/ holds the research tools (ft-eyes-score, -e2e, -record, -replay,
-session) and findings.md. Recordings live outside the repo, in
~/.local/share/frametop/eyes/captures; .gitignore catches stray frame dumps.
Its socket is now @ft_eyes, its output /dev/shm/frametop-eyes-gaze, and its state
~/.local/state/frametop/gaze/eyes. On practice1 -> practice2 the whole live path
(ft-eyes-e2e) gives 1.30 deg median and 3.18 for the worst tenth, as before the
move (1.30, 3.21).
